This communication presents the treatment of 15 cases of c-shaped canals in molars and their treatment outcome with two different obturation methods. The data from 901 patients who received root canal treatment in a molar tooth were examined regarding c-shaped root canals, their treatment and their status one year post op. Among the 901 cases, 15 molars had a c-shaped root canal morphology (1,6...

The bond strength of ActiV GP and gutta-percha/AH Plus after using 2% CHX as final rinse was evaluated in this study. According to the final irrigation regimen forty roots were divided into two groups (n = 20) randomly: Group 1-5 ml of 17% EDTA; Group 2-5 ml of 17% EDTA followed by 5 ml of 2% chlorhexidine gluconate (CHX). Based on the obturation system the two groups were further subdivided in...

Overinstrumentation during root canal treatment is one of the causes for iatrogenic enlargement of the root apex. It also leads to unwarranted coronal third widening, which results in thinning of the dentinal walls and makes the tooth susceptible to fracture. Another difficulty arises during control of obturation material within the canal. Such cases can be managed with obturation using mineral...

Root fractures are relatively uncommon among other dental traumas and mostly affect the anterior dentition. This case report presents the endodontic and prosthodontic management of a maxillary central incisor with a combined fracture in the middle third of the root and the crown, as well as the 7-year follow up of the case. The healing potential of a horizontal root fracture in the middle third...

NTRODUCTION The goals of root canal therapy are to remove infected and necrotic pulpal tissue remnants, shape the root canal system to facilitate irrigation and medication and adequate sealing using obturation materials. 1 Rotary instruments enhance the quality of obturation by providing conical shape to the root canal. Nickle titanium (NiTi) alloy instruments inherent flexibility that allows t...

Micro-endodontics has emerged as a critical component in endodontics, revolutionizing the management of complex root canal anatomy. It utilizes magnification devices, such dental operating microscopes or loupes, to enhance visualization and identify intricate anatomical details. encompasses advanced techniques technologies that are utilized alongside principles conventional endodontics. While b...

background: the aim of the present study was to investigate the quality of root canal obturation performed by 6th year undergraduate dental students at the dental school, university of mashhad, iran. materials and methods: a random 200 sample records of patients who received endodontic treatment at the dental school, university of mashhad between 2009 and 2010 was investigated. the quality of r...

The long-term success of root canal treatment requires the prevention bacterial leakage between walls and obturation. In this study, we compared Enterococcus faecalis in thirty single-rooted mandibular premolars divided into three groups. roots two experimental groups were obturated using a single-cone obturation technique with different bio-ceramic sealers (MTA Fillapex CeraSeal) while convent...

A prospective in vivo investigation was conducted to determine radiographic and clinical factors associated with contemporary nonsurgical endodontic retreatments. Approximately 1,100 failing endodontically treated teeth were screened to determine an appropriate treatment plan. Using magnification, 337 consecutive retreatment cases were evaluated and treated. The vast majority of the retreated c...
